**Power-Pico** is more than just a USB ammeter. It is a **high-precision, low-power analysis tool** designed specifically for embedded developers. To overcome the physical limitations of traditional ammeters in the μA-level measurement, Power-Pico adopts an innovative **multi-range auto-switching sampling** design, achieving full-range coverage from $1\mu A$ to $5A$. **Power-Pico** is more than just a USB ammeter.
